Definitions
- the present invention relates to a method for the diagnostic detection of apoptosis in cells and a kit that can be used for this.
- the object of the present invention is therefore to provide a method with which the extent of apoptosis in cells can be reliably estimated.
- ICE proteases precedes the morphologically measurable apoptotic cell death and the occurrence of DNA strand breaks by several hours and is therefore an early parameter of apoptosis in otherwise intact cells.
- ICE / Ced3 proteases is an early event in cells in which the apoptosis program has been irreversibly induced.
- the invention is now based on the knowledge of the inventors that early events associated with the induction of intracellular apoptosis programs can be detected at the molecular level by the traceable activation of the ICE / Ced3 proteases.
- Samples of patients who are undergoing apoptosis-inducing or apoptosis-inhibiting therapy are preferably measured ex vivo. With the method according to the invention it is therefore possible to reliably determine the effect of therapies on the basis of the induction or inhibition of apoptosis ex vivo or in vivo on intact cells.
- the activation of the ICE / Ced3 proteases is detected by means of an imaging (optical) method, preferably a flow-cytometric method.
- an imaging (optical) method preferably a flow-cytometric method.
- intact cells are loaded with substrates for ICE / Ced3 proteases after permeabilization.
- Permeabilization can take place, for example, by adding water to the cells (osmotic shock) or by the action of digitonin or other permeabilizers.
- the permeabilization preferably takes place to such an extent that 10% of the cells subsequently appear as living in the forward / side scatter.
- Suitable substrates for the ICE / Ced3 proteases have at least one aspartyl group.
- the protease substrates are preferably fluorogenic for carrying out a flow cytometric measurement. Suitable Substrates are described in "Matayoshi et al., Science 247, pp. 954-958 (1 990)".
- a fluorogenic substrate is preferably used in which 5 - [(2-aminoethyl) amino] naphthalene-1-sulfonic acid (EDANS) is the fluorogenic donor and 4- (4-dimethylaminophenylazo) benzoic acid (DABCYL) is the quenching acceptor, wherein donor and acceptor are connected to one another by means of a spacer.
- DABCYL-YVADAPK-EDANS or DAB-CYL-DEVDAPK-EDANS are very particularly preferably used.
- Coumarin-related substrates such as DEVD-NMA can also be used.
- Rhodamine 110 derivatives are also suitable in which amino groups are substituted with various individual amino acids or short caspase substrate peptides.
- the intracellular protease activity is measured optically, preferably by means of a flow cytometer, as the fluorescence of the cleaved substrate.
- the method enables cells to be identified using surface markers in simultaneous measurement, ie for different cells it can be determined exactly which cells are still alive and which have died.
- the advantages of the method according to the invention are that it can be carried out quickly and easily and enables sensitive detection.
- the detection of apoptosis is possible several hours before morphologically detectable changes occur in the cells and is not influenced by the removal of apoptotic cells by the reticuloendothelial system in vivo.
- the method according to the invention can also be carried out using a kit. This contains a protruding substrate for proteases of the ICE / Ced3 family, the substrate being in particular fluorogenic.
- Substrates such as DAB-CYL-YVADAPK-EDANS, DABCYL-DEVDAPK-EDANS, DEVD-NMA or rhodamine 110 derivatives are very particularly preferred in which amino groups are substituted with various individual amino acids or short caspase substrate peptides.

- Fig. 3 Measurement of doxorubicin-induced ICE / Ced3 activity and cell death (maximum 33342 / propidium iodide) in CEM cells in a time kinetics
- ICE / Ced3 activity (squares) can be detected 2-4 hours before the first DNA changes that show apoptotic cell death (diamonds).
- CEM cells that were treated for 1 hour with a CD95-specific antibody (anti-APO-1; 1 ⁇ g / ml) (see Oehm, A. et al., The Journal of Biological Chemistry, Volume 267, No. 1 5 (1 992), pp. 10709-1071 5), are cultivated in cell culture medium RPMI 1 640 + 10% FCS. 10 ⁇ ⁇ ICE / Ced3 substrate DABCYL-YVADAP-EDANS (stock solution 100 mM in DMSO; stored at -70 ° C.) are added. Water (the same volume as the cell culture medium) is added to permeabilize the cells.
- RPMI 1 640 + 10% FCS 10 ⁇ ⁇ ICE / Ced3 substrate
- DABCYL-YVADAP-EDANS stock solution 100 mM in DMSO; stored at -70 ° C.
- the mixture is incubated for 5 minutes at 37 ° C before ice cold 5x PBS in 50% FCS (0.25 volume of the initial volume) is added to bring the osmolarity back to normal.
- the mixture is stored on ice and in 2 hours in Measure the flow cytometer.
- the excitation wavelength of the substrate used is - 360 nm and the emission is measured at 488 nm.
- untreated CEM cells are subjected to the same procedure.
- CEM cells that were treated for 2 hours with a CD95-specific agonistic antibody (anti-APO-1; 1 ⁇ g / ml) (see Oehm, A. et al., The Journal of Biological Chemistry, volume 267, No. 1 5 (1 992), pp. 10709-1071 5), are cultivated in cell culture medium (RPMI 1 640 + 10% FCS).
- RPMI 1 640 + 10% FCS cell culture medium
- 100 l of ICE / Ced3 substrate DABCYL-YVADAP-EDANS stock solution 100 mM in DMSO; stored at -70 ° C.
- digitonin in a final concentration of 0.002-0.005% (preferred concentration: 10% of the cells appear afterwards)
- Permeabilization added as living in forward / side-scatter).
- the mixture is incubated at 37 ° C for 5 minutes before an equal volume of ice-cold cell culture medium or PBS is added to dilute the digitonin.
- the mixture is stored on ice and measured in the flow cytometer within 2 hours.
- the excitation wavelength of the substrate used is - 360 nm and the emission is measured at 488 nm.
- untreated CEM cells are subjected to the same procedure.
- variant 2 is more effective, however the cells treated according to variant 1 provide a lower background.
- CEM cells that have been treated with doxorubicin (1 ⁇ g / ml) are cultivated in cell culture medium (RPMI 1 640 + 10% FCS).
- Permeabilization added as living in forward / side-scatter.
- the mixture is incubated at 37 ° C for 5 minutes before an equal volume of ice-cold cell culture medium or PBS is added to dilute the digitonin.
- the mixture is stored on ice and measured in the flow cytometer within 2 hours.
- the excitation wavelength of the substrate used is - 360 nm and the emission is measured at 488 nm.
- the recorded time kinetics is shown in FIG. 3. It can be seen from this that the ICE / Ced3 activity is detectable long before the onset of cell death and provides a reliable indication of apoptosis that has started.
- Jurkat cells are treated for 1.5 hours with a CD95-specific antibody (anti-APO-1). They are then treated as described in variant 1 of example 1.
- a CD95-specific antibody anti-APO-1
- the caspase substrate D 2 rhodamine is added to a final concentration of 50 ⁇ M.
- the caspase activity is measured in a flow cytometer (FACScan, Becton Dickinson).
- the excitation wavelength is 488 nm.
- the fluorescence is measured in the FL1 photomultiplier.
- the dotted line shows the control cells that were not treated with the anti-CD95 antibody.
- the solid line shows the fluorescence shift after antibody treatment. An increase in dead cells can only be detected by propidium iodide staining 3 hours after antibody treatment.
- untreated Jurkat cells are subjected to the same procedure throw.
